Race Build Turbo: Progressive 60-Minute FTP Effort

Session Overview

This progressive turbo session mimics real triathlon bike pacing — starting conservative in zone 2 and building through sweet spot into race effort over 60 minutes. It trains your body to tolerate increasing intensity without blowing up, directly replicating the demands of a well-paced Olympic or 70.3 bike leg.

What You’ll Need

  • Turbo trainer or smart trainer
  • Power meter or ERG mode on a smart trainer
  • Fan for cooling
  • Hydration — 500ml minimum per 30 minutes

Warm-Up (10 minutes)

10 minutes at 50–55% FTP in ERG mode or easy resistance. Cadence at 90–95rpm. Include 3×20-second openers at 90% FTP (with 40 seconds easy between) in the final 3 minutes to prime your neuromuscular system without using glycogen.

Main Set

The session builds in three 12-minute blocks, each at progressively higher intensity. This structure trains your body to accelerate late in the race — when most athletes are fading. If you don’t have a power meter, use RPE targets.

  • Block 1 — 12 minutes: 75–80% FTP (zone 2/aerobic), RPE 5/10 — this should feel easy
  • 2 minutes easy at 50% FTP
  • Block 2 — 12 minutes: 85–90% FTP (sweet spot), RPE 6.5–7/10 — working but sustainable
  • 2 minutes easy at 50% FTP
  • Block 3 — 12 minutes: 95–100% FTP (threshold), RPE 8/10 — hard but controlled; maintain cadence above 88rpm
  • 2 minutes easy at 50% FTP
  • Final 4 minutes: 105% FTP (above threshold), RPE 8.5–9/10 — this is the race finish effort; hold form

Cool-Down (8 minutes)

8 minutes at 40–50% FTP, cadence 85–90rpm. Spin your legs out rather than stopping abruptly. Use this time to rehydrate and mentally note how each block felt.

Coaching Notes

  • The purpose of the 2-minute easy blocks is not full recovery — just enough to reset breathing and lower heart rate before the next block begins
  • If your FTP is outdated, reduce block 3 target to 90% and the final 4 minutes to 100% until you re-test
  • Easier version: reduce all blocks by 5% FTP, or replace the final 4-minute effort with an easy spin
  • This session pairs well with a short 20-minute brick run immediately after the cool-down
  • Cadence should not drop below 85rpm in any block; if it does, reduce resistance rather than grinding
